This beautiful 20 centimes stamp from Rwanda, issued in 1979, features the Alienus Weaver (Ploceus alienus), a vibrant bird native to Central and East Africa. Illustrated by the artist Severin, the design captures the weaver’s distinctive yellow plumage, olive wings, and contrasting black head with red throat shading. The light botanical background enhances the bird’s elegance, typical of Rwanda’s late-1970s natural history series. A fine collectible for both African ornithology and wildlife-themed philately.
